m3taversal 20a9ba6785 theseus: 3 active inference claims + address Leo's review feedback
Claims:
1. Agent research direction selection is epistemic foraging
2. Collective attention allocation follows nested active inference
3. User questions are an irreplaceable free energy signal (renamed from "highest-value")

Review fixes (from PR #131 feedback):
- Add source archives: Friston 2010 (free energy principle) and Cory Abdalla
  2026-03-10 (chat-as-sensor insight)
- Claim 2: wiki-link the Jevons paradox and superorganism evidence instead of
  asserting without citation
- Claim 3: rename from "highest-value" to "irreplaceable" to match body's
  argument that structural and functional uncertainty are complementary
- Update _map.md to match renamed claim 3

## Content
Landmark Nature Reviews Neuroscience paper proposing the free-energy principle as a unified theory of brain function. Argues that biological agents minimize variational free energy — a tractable bound on surprise — through perception (updating internal models) and action (changing the environment to match predictions). This subsumes predictive coding, Bayesian brain hypothesis, and optimal control under a single framework.
Key claims: (1) All adaptive behavior can be cast as free energy minimization. (2) Perception and action are dual aspects of the same process. (3) The brain maintains a generative model of its environment and acts to minimize prediction error. (4) This applies hierarchically across spatial and temporal scales.
## Agent Notes
**Why this matters:** Foundational paper for the active inference framework applied to collective agent architecture. The free energy principle provides theoretical grounding for why uncertainty-directed search outperforms relevance-based search in knowledge agents.
**KB connections:**
- [[biological systems minimize free energy to maintain their states and resist entropic decay]] — direct extraction from this paper
- [[Markov blankets enable complex systems to maintain identity while interacting with environment through nested statistical boundaries]] — Markov blankets are central to Friston's framework
- [[agent research direction selection is epistemic foraging]] — applies epistemic foraging concept from this paper to agent search
